An iron(II)-catalyzed nitrene transfer reaction of sulfoxides with -acyloxyamides has been developed, leading to the efficient construction of acyl sulfoximines with high functional-group compatibility. The current catalytic transformation was carried out under an air atmosphere at ambient temperature and could be scaled up to gram scale with a catalyst loading of 1 mol %. Application of the methodology was demonstrated by facile C-H acetoxylation and olefination using the acyl sulfoximine as the directing group.
已开发出一种铁(II)催化的亚砜与酰氧基酰胺的氮烯转移反应,可高效构建具有高官能团兼容性的酰基亚砜亚胺。当前的催化转化在空气气氛下于室温进行,且催化剂负载量为1 mol%时可放大至克级规模。使用酰基亚砜亚胺作为导向基团,通过简便的C-H乙酰氧基化和烯烃化反应证明了该方法的实用性。
